Morphology
vena + comitans
This is a Latin anatomical term: while 'vena' corresponds to English 'vein', 'comitans' is not an English word and is not found in the learner's dictionary, so a B1 learner who merely 'knows the constituents' would not reliably infer 'accompanying' or the anatomical sense. The label is also highly technical and Latinized rather than a transparent English composition, making its meaning unpredictable without prior exposure or specialist knowledge.
Etymology
Vena comitans comes from Latin words vena meaning 'vein' and comitans meaning 'companion'. The phrase paints a simple picture of a vein walking right beside an artery so the artery's pulse helps push blood along, which is why it means a vein that runs alongside an artery.
